Beschreibung
Zusammenfassung:	The invention relates to a manufacturing technology for YDB sound absorption and thermal insulation materials. The manufacturing technology sequentially comprises the following steps: (1) melt-blowing, (2) filling, (3) non-composite fabric compositing, (4) hot rolling, (5) slitting, (6) product inspection and (7) packaging. Compared with a traditional production technology and process for automobile sound absorption and thermal insulation materials, the project production technology and process are provided with the filling process, formed polyester staple fibers are disorganized and mixed, a transformed cotton-blowing machine is adopted to conduct internal cotton blowing on formed cotton (so as to increase the density of the cross section), and manufacturing of products being processed is completed through the rotary screen web formation process.
